not sure if this is the same bug, don't want to make duplicate posts
i used the search function 3-4 times
this was fine in the early 1.5 snapshots, I found the glitch happen in 13w05a first, and found it still broken even though it says its fixed
It happened in 13w05a, it makes the closing mechanism of redstone portcullis not work correctly.
Iron golems and villagers do this too. Also the golems randomly swing their arms even though there are no monsters. (12w50b)
oh i thought this was a bug, cause they have fish items but no mobs
this is the biggest bug since the Halloween update last year
wow this means that i had 2 bugs at once in 13w05b for MC-8992 so i guess it wasnt 100% duplicated
